Free HTTP Headers Inspector
View all HTTP response headers for any domain. Follow redirect chains and detect stack information leakage via Server and X-Powered-By headers.
Why inspect HTTP headers?
HTTP response headers reveal a lot about a server — its software, version, caching behavior, and security posture. Security-sensitive headers like Server and X-Powered-By can expose your tech stack to attackers. Missing security headers leave you vulnerable to XSS, clickjacking, and data leakage.
